Summed tolerance for calibration calculations
You can use summed tolerance criteria for each tolerance level. Summed tolerance is the total of single tolerance expressions.
The calculation converts the individual terms to corresponding output units and then adds all the output units together.
Summed Tolerance = Desired Output + EU + %Span + %URV + %Reading
